LOOSE-LEAF BINDER.

Specification of Letters Patent.

Patented Oct. 15, 1912.

Appltcatlon filed March 7, 1912. Serial No. 682,197.

, invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in loose leaf book covers orbinders and is designed as an improvement over the binder shown in myPatent #906,365, dated December 8, 1908:

The object of the invention is to provide a binder or cover of thischaracter having means for permitting the removalfrom the book of theloose leaves without unlacing the binding cord.

With these and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement .of partsas will be more fully escribed hereinafter and claimed.

In the accompanying drawin s; Figure 1 represents a plan view of theront face of a book equipped with this invention; Fig. 2 is a view ofthe rear face of the book; Fig. 3 is a plan ,view of the inside of abook opened out flat; Fig. 4 is a longitudinal section taken on line 4-4of Fig. 1; Fig. 5 is a plan view of the outer side of the cover showinthe manner in which the binding cord 1s released to permit the coversections to be opened out flat; Fig. 6 is a transverse section of thebook with the covers opened back to back for use on the arm of a chair.

. In the embodiment of the invention front and back cover sections 1 and2 are provided each of which consists of a main or body portion 3 and ahinge strip 4. These parts may be made of paper board or any suitablematerial and the ody portion 3 is preferably connected tothe hinge strip4 by the fabric covering of the boards, said covering being applied tothe body portion and binge strip n one piece as shown.

In each hinge strip 4 of each cover section is arranged a series ofeyelets 5 so when the cover sections are in proper position on theleaves of the book they will be in alinement, and a binding cord 6 isadapted to be passed through said alined eyelets. The binding cord hasformed therein near one end a knot 6 and in applying the cord to thecover sections the longer end of the cord is passed through theregisteringjeyeletsat one end and then through the registering eyeletsat the other end and this end of the cord is provided with a fasteningdevice preferably in the form of a resilient socket 7 which is adaptedto engage with a stud 8 secured to the outer face of the hinge strip ofone of the cover sections preferably at a point about midway of thelength of said strip, when this end of the cord is drawn through theeyelets far enough to allow the socket '4' to be engaged with the stud8.

Then it is desired to open the book out flat the socket 7 is disengagedfrom the stud S which will permit the cord to be drawn through theeyelets thus permitting slack in the loop formed between the eyeletswhich will permit the cover sections .to be drawn apart a greater orless distance according to the length of the loop and the length of thecord whereby the cover sections may be laid flat and the leaves openedout thereon. This arrangement greatly facilitates the use of the bookfor many purposes and enables a ruler to be laid flat across the pages.In constructing the cover or hinder the cord should be of sutlicientlength to permit the loop between its ends to be loosened when desiredto accommodate additional leaves which may from time to time be added tothe book and by tying a loop at the other end of the cord the same maybe readily released when desired such for instance as in thesubstitution of a new cord.

The cover above described is the same as that shown in the Meat abovereferred to and it will be obvious that whenthis construction isemployed it is necessary to thread the binding cord through aperturesformed in the rear edge of the leaves to be bound. and to remove one ofsaid leaves or to insert a new one necessitates the unlacing andrelacing of the binding cord, at least the releasing of the ends thereofand the 'removal of one of the'covers. It is to obviate theseobjectionable features that this invention is designed and whichconsists in providing one of the hinge members 4 on its inner face witha plurality of longitud1- ,nally spaced laterally projecting studs 10.two being here shown arranged between the signed to be passed throughapertures 1'1 formed in the rear edges of the leaves 12 to be bound, asshown clearly in Fig. 1, said apertures being formed by a suitablepunch.

These leaves 12 are also provided at their rear edges at pointsregistering with the cord apertures in the hinge members with apertures13 whichopen through the rear edges E of the leaves to provide for thesliding of i the leaves from the binding cord at opposite ends of thebinder as shown clearly in Fig. 1. 5 Vhen'it is desired to place a newleaf 12 on the binder all that is necessary is to release the socket 7from the stud 8 and;

, open the binder into fiat position shown in Fig. 1 when a leaf 12having apertures 11 1 and 13 described above therein may be engaged withthe studs 10 and the bindingi cord in the manner described.

The other hinge member 4 of the other cover is provided with a pluralityof ap ertures 14 arranged to register with the studs 10 on the hingemember of the cooperating cover and said studs are adapted to passthrough said apertures 14 when the covers are in closed binding.position. It

will thus be seen that a leaf may be applied to or removed from the bookwithout interfering with the lacing cord,

Iclaim as my invention:

1. A loose leaf binder comprising front and back cover sections havingnear their rear edges a series of alined eyelets or ap ertures, aflexible binding element laced through said eyelets and. fastened at oneend, means for fastening the free end of said binding element when saidelement is drawn tight, studs extending laterally from the inner face ofone of said cover sections the other section having eyelets arrangednear its rear edge inposition to register with the studs of thementioned section and adapted to be engaged therewith.

3. A loose leaf binder comprising front and back cover sectionshavingnear their rear edges a series of alinegl eyelets or apertures, aflexible binding element laced through said eyelets and fastened atoneend, means for fastening the free end of said binding element when saidelement is drawn tight, studs extending laterally from the inner iace ofone of said cover sections the other section having eyelets arranged thestuds of one of the cover sections and open slots disposed to registerwith the eyelets through which the binding element passes.

'3. The combination with a loose leaf binder comprising front and rearsections having a series of alined eyelets near their rear edges, aflexible binding element laced through said eyelets, one of saidsections having laterally extending longitudinally spaced studs ofdetachable leaves having apertures positioned to register with the studsof the cover section and slots opening through the rear edge thereofpositioned to register with the eyelet through which the binding elementpasses.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
